Built a nice little PiKVM and deployed it in my NAS. The NAS is heavy and placed in a dark half-height place under the stairs so it’s awkward when things go wrong and you need hardware access.

Exactly, it isn’t a replacement. It is redundancy in the form of a screen with keyboard and mouse directly connected, but accessibly from remote (my couch). It is far from my primary interface with the server.
